To all whom it may concern: I

Be it known that 1,.GLARENCEE; DRAKE, a citizen of the United States,residing at Union, in the county of Broome and State of New York, have inventedcertain new and useful Improvements in Door-Holders, of which the following is a specification.

My invention relates particularly to a device adapted to hold a door in an open position after it has once been opened. It is particularly adapted for use in factories and the like where fire-doors are employed so that once a fire-door is opened, it cannot be again closed accidentally but the means of my invention must be released manually to permit closing of the door. It often happens that in fires in factories, the fire-doors become closed accidentally and thus prevent the escape of the occupants of the building due to the fact that, the panic arising as a result of the fire, persons entrapped are unable to open the door and maintain it in an open position. It is the prime object therefore, to provide a device 7 which will eliminate this difficulty.

Another object of the present invention is to provide a device of the character set forth which is simple in construction, comprises a minimum number of parts, and is efficient in use.

WVith the above and other objects in view, I will proceed to describe one specific embodiment of the present invention with ref erence to the accompanying drawings wherein such embodiment is illustrated andwhich forms a part of the present specificatlon.

In the drawings:

Figure 1 is a side elevation of a portion of a door of the sliding type equipped with a device embodying my invention.

Fig. 2 is a view similar to Fig. 1 but showing the door in open position, and

Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

In detail:

The device as shown is applied to a door A having a casement or frame B. The door is of any suitable sliding type, or it may be of the swinging type, and the device itself comprises a toggle indicated at C.

The toggle comprises two arms 1 and 2, the end of one being pivoted intermedlate the ends of the other as shown at 3. end of the toggle C is pivoted to the door frame B as shown at 4 whereas the other end is pivoted to the door A as shown at 5 One and thus as the door A is moved to the openposition, the toggle members 1 and 2 will .be pulled. out into. alinement with eachother. It is to be noted that, due to the fact that the arm 2 is pivoted intermediate the ends of the arm 1, a free end 6 is provided on the arm 1 and this end carries two lips 7 and 8 which are bent or offset with respect to the main portion to provide a clip which will engage the arm 2 as the toggle is straightened out and thus will, when the door is in the position shown in Fig. 2 and the toggle arms in alinement, prevent said arms from buckling with respect to each other with the result that any push or force applied to the door with the intention of closing it will not act successfully due to the fact that a straight, rigid arm or member formed by the toggle arms coming into alinement will resist such closing effort and maintain the door in an open position.

Attached to the portion 6 of the arm 1 is an eye 9 carrying a chain 10 provided with a finger ring 11 and when the toggle is straightened out as shown in Fig. 3, a slight pull on the finger ring 11 will be sufficient to cause the toggle to buckle and permit the door to close.

WVhile, in the foregoing, I have described and illustrated a specific embodiment of the present invention, it is nevertheless to be understood that, in practice, I may resort to such practical modifications as fall within the scope of the invention as defined in the appended claims. And I may apply the device to swinging doors or windows or sliding doors and windows, without departing from the spirit of the invention.

I claim:

1. The combination with a door and frame, of a toggle connecting the said door and frame, one link of said toggle being longer than the other and the shorter link being pivoted to the longer link inwardly from the outer end thereof, and lips projecting laterally from the longitudinal edges of one of said links for engagement with the corresponding edges of the opposing link when said links are alined.

2. The combination with a door and frame, of a toggle connecting the said door and frame, one link of said toggle being longer than the other, and the shorter link being pivoted to the longer link inwardly from the outer end thereof, lips projecting from the longitudinal edges of said longer link at the free end thereof, said lips being bent inwardly out of the plane of said longer link and then being flared outwardly, and a chain connected to the said free end of said longer link.

3. The combination with a sliding. door and frame, of a toggle link having one end pivoted to the door frame and the other end pivoted to the door, said toggle being arranged to straighten out as the door is moved to the open position, lips carried by one part of the toggle for engagement with Copies of this patent may be obtained for the other part thereof when the toggle parts are in alinement to prevent the toggle from breaking and thereby hold the door in an open position, and means for manually bending said toggle to permit closing of the door.

In testimony whereof I affix my signature in presence of two witnesses.
